Ned Deilycbfb9a52012-06-23 16:02:19 -0700641- Issue #13590: Improve support for OS X Xcode 4:
642 * Try to avoid building Python or extension modules with problematic
643 llvm-gcc compiler.
644 * Since Xcode 4 removes ppc support, extension module builds now
645 check for ppc compiler support and automatically remove ppc and
646 ppc64 archs when not available.
647 * Since Xcode 4 no longer install SDKs in default locations,
648 extension module builds now revert to using installed headers
649 and libs if the SDK used to build the interpreter is not
650 available.
651 * Update ./configure to use better defaults for universal builds;
652 in particular, --enable-universalsdk=yes uses the Xcode default
653 SDK and --with-universal-archs now defaults to "intel" if ppc
654 not available.

1435 and lifetime issues of dynamically allocated Py_buffer members (#9990)
1436 as well as crashes (#8305, #7433). Many new features have been added
1437 (See whatsnew/3.3), and the documentation has been updated extensively.
1438 The ndarray test object from _testbuffer.c implements all aspects of
1439 PEP-3118, so further development towards the complete implementation
1440 of the PEP can proceed in a test-driven manner.
1441
1442 Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
1443 and many ideas.

1713 and its type get caught in a reference cycle, and the instance's
1714 deallocator calls one of the methods on the type (e.g. when subclassing
1715 IOBase). Diagnosis and patch by Davide Rizzo.

Ned Deily99377482012-02-10 13:01:08 +01002011- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2012 Distutils-based packages with C extension modules may fail because
2013 Apple has removed gcc-4.2, the version used to build python.org
2014 64-bit/32-bit Pythons. If the user does not explicitly override
2015 the default C compiler by setting the CC environment variable,
2016 Distutils will now attempt to compile extension modules with clang
2017 if gcc-4.2 is required but not found. Also as a convenience, if
2018 the user does explicitly set CC, substitute its value as the default
2019 compiler in the Distutils LDSHARED configuration variable for OS X.
2020 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2021 SDK, neither of which are available in Xcode 4. This change does not
2022 attempt to override settings to support their use with Xcode 4.)

2748
Ned Deily657b2de2011-06-28 19:51:30 -07002749- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2750 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2751 interpreter process. This could cause failures in non-Distutils subprocesses
2752 and was unreliable since tests or user programs could modify the interpreter
2753 environment after Distutils set it. Instead, have Distutils set the the
2754 deployment target only in the environment of each build subprocess. It is
2755 still possible to globally override the default by setting
2756 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2757 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07002758 was built. Also, implement the same handling in packaging.

Nick Coghlan793ee1f2011-01-30 01:24:08 +00003888- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
3889 files in binary mode, using the email package's binary support to parse
3890 arbitrary email messages. StringIO and text file input is deprecated,
3891 and string input fails early if non-ASCII characters are used, where
Éric Araujoac4e58e2011-01-29 20:32:11 +00003892 previously it would fail when the email was processed in a later step.

3902
3903- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
3904 preventing a confusing hung appearance on OS X with the windows
Victor Stinner80f75e62011-01-29 11:31:20 +00003905 obscured.
3906
Raymond Hettinger8b5eb2f2011-01-27 00:06:54 +00003907- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
3908 menu accelerators for Open Module, Go to Line, and New Indent Width.
3909 The accelerators still work but no longer appear in the menu items.

Raymond Hettinger512d2cc2011-01-25 21:32:39 +00003917 with a None body.
3918
Ned Deily122539e2011-01-24 21:46:44 +00003919- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
3920 keyword-only argument. The preceding positional argument was deprecated,
3921 so it made no sense to add filter as a positional argument.
Raymond Hettingerbf1d2bc2011-01-24 04:52:27 +00003922
3923- Issue #11004: Repaired edge case in deque.count().

3926 with non-ASCII characters in their path names.
Georg Brandlc7c199f2011-01-22 22:06:24 +00003927
3928- Have hashlib.algorithms_available and hashlib.algorithms_guaranteed both
Victor Stinnerf2e439f2011-01-23 00:11:58 +00003929 return sets instead of one returning a tuple and the other a frozenset.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00003936 filenames, at bootstrap, if the codec registry is not ready yet. It is still
3937 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
3938 for all file entries in the ZIP file.
Antoine Pitroue47e0932011-01-19 15:21:35 +00003939

3947
3948- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
3949 encoding. This is the preferred encoding of PEP 3333 and the base encoding
3950 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00003951
3952- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00003953 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00003954 that for incoming headers which makes this behaviour now consistent in
3955 both incoming and outgoing direction.
3956
Georg Brandl0f6b47a2011-01-30 12:19:35 +00003957- Issue #9509: argparse now properly handles IOErrors raised by
3958 argparse.FileType.

3990
Victor Stinnerb3c9e072011-01-04 02:07:34 +00003991- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
3992 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
3993 translates newlines (\r\n => \n).
3994
Victor Stinnerdc555402011-01-04 13:15:39 +00003995- Remove buffer API from stable ABI for now, see #10181.

Georg Brandl255abdd2011-01-16 14:17:26 +00004029- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
4030 than the currently problematic Apple-supplied one, when running with the
4031 64-/32-bit installer variant.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00004051- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00004052 continuation line in the formatted value has no leading white space and looks
4053 like a header. Since Generator uses Header to format all headers, this check
4054 is made for all headers in any serialized message at serialization time. This
4055 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00004056

Georg Brandl255abdd2011-01-16 14:17:26 +00004065 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00004066
Éric Araujof0ab5d62011-05-29 03:43:59 +02004067- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00004068 rfc2047-encoding header values with embedded newlines, leaving them without
4069 folding whitespace. It now uses the continuation_ws, as it does for
4070 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00004072- Issue #1777412, #10827: Changed the rules for 2-digit years. The
4073 time.asctime(), time.ctime() and time.strftime() functions will now format
4074 any year when ``time.accept2dyear`` is False and will accept years >= 1000
4075 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
4076 supported by the OS. With Visual Studio or on Solaris, the year is limited to
4077 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00004713 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00004714 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00004715 encoding and to encode command line arguments on this OS.

4718 filenames encoded to the filesystem encoding with the surrogateescape error

4720
Benjamin Peterson230b2062010-10-16 03:45:45 +00004721- Issue #9997: Don't let the name "top" have special significance in scope

5099
Georg Brandl27a28582010-10-10 09:49:21 +00005100- All SyntaxErrors now have a column offset and therefore a caret when the error

5110 with a non-empty format string. This is an effort to future-proof user
5111 code. If a derived class does not currently implement __format__ but later
5112 adds its own __format__, it would most likely break user code that had
5113 supplied a format string. This will be changed to a DeprecationWaring in
5114 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00005116- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
5117 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
5118 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
5119
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00005120- Issue #9210: Configure option --with-wctype-functions was removed. Using the
5121 functions from the libc caused the methods .upper() and lower() to become
5122 locale aware and created subtly wrong results.
5123
Georg Brandl27a28582010-10-10 09:49:21 +00005124- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
5125 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00005126
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00005127- Issue #4617: Previously it was illegal to delete a name from the local
5128 namespace if it occurs as a free variable in a nested block. This limitation
5129 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
5130
Georg Brandl27a28582010-10-10 09:49:21 +00005131- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
5132 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
5133 Also, the "backslashreplace" error handler now joins surrogate pairs into a
5134 single character on UCS-2 builds.

5137 underlying buffer (previously this was only done when deallocating the
5138 memoryview), and gain support for the context management protocol.
5139
Antoine Pitrou079ce542010-09-08 12:37:10 +00005140- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00005169- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005170 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00005171 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005172 replacement for old handle_accept() and avoids the user to call accept()
5173 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00005196- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00005197 retry the select() loop instead of bailing out. This is because select() can
5198 incorrectly report a socket as ready for reading (for example, if it received
5199 some data with an invalid checksum).

Vinay Sajipc84f0162010-09-21 11:25:39 +00005239- logging: hasHandlers method was added to Logger, and isEnabledFor,
5240 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
5241 LoggerAdapter was introduced into the unit tests for logging.

5244
Antoine Pitrou98b46702010-09-18 22:59:00 +00005245- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00005246 non-blocking mode: they return None when an operation would block (instead of
5247 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00005248
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00005249- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

5257 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00005258
Georg Brandl27a28582010-10-10 09:49:21 +00005259- Issue #1552: socket.socketpair() now returns regular socket.socket objects
5260 supporting the whole socket API (rather than the "raw" _socket.socket
5261 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00005262

Raymond Hettingerfa11db02010-09-12 04:12:42 +00005279- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00005280 it possible for the user to create self-referencing ordered dictionaries which
5281 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00005282 approach of using weakref proxies so that reference cycles never get created
5283 in the first place.
5284
Victor Stinnercb043522010-09-10 23:49:04 +00005285- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
5286 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00005287 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00005288
Georg Brandl27a28582010-10-10 09:49:21 +00005289- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
5290 environment variable to set the filesystem encoding at Python startup.
5291 sys.setfilesystemencoding() creates inconsistencies because it is unable to
5292 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00005293
Georg Brandl27a28582010-10-10 09:49:21 +00005294- Issue #9410: Various optimizations to the pickle module, leading to speedups
5295 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
5296 initial patch by Alexandre Vassalotti.

Georg Brandl27a28582010-10-10 09:49:21 +00005298- The pprint module now supports printing OrderedDicts in their given order
5299 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00005301- Logging: Added QueueHandler class to facilitate logging usage with
5302 multiprocessing.
5303
Georg Brandl27a28582010-10-10 09:49:21 +00005304- Issue #9707: Rewritten reference implementation of threading.local which is
5305 friendlier towards reference cycles. This change is not normally visible
5306 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00005307
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00005308- Issue #6394: os.getppid() is now supported on Windows. Note that it will
5309 still return the id of the parent process after it has exited. This process
5310 id may even have been reused by another unrelated process.
5311
Georg Brandl27a28582010-10-10 09:49:21 +00005312- Issue #9792: In case of connection failure, socket.create_connection() would
5313 swallow the exception and raise a new one, making it impossible to fetch the
5314 original errno, or to filter timeout errors. Now the original error is
5315 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00005316
Georg Brandl27a28582010-10-10 09:49:21 +00005317- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
5318 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
5319 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00005321- Updates to the random module:
5322
Georg Brandl27a28582010-10-10 09:49:21 +00005323 * Document which parts of the module are guaranteed to stay the same across
5324 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00005325
Georg Brandl27a28582010-10-10 09:49:21 +00005326 * Update the seed() method to use all of the bits in a string instead of just
5327 the hash value. This makes better use of the seed value and assures the
5328 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00005329
Georg Brandl27a28582010-10-10 09:49:21 +00005330 * Improved the random()-->integer algorithm used in choice(), shuffle(),
5331 sample(), randrange(), and randint(). Formerly, it used int(n*random())
5332 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00005333
5334 * Improved documentation of arguments to randrange(). Issue #9379.

5340 cases now also have assertWarns and assertWarnsRegexp methods to check that a
5341 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +00005353- hashlib has two new constant attributes: algorithms_guaranteed and
5354 algorithms_avaiable that respectively list the names of hash algorithms
5355 guaranteed to exist in all Python implementations and the names of hash
5356 algorithms available in the current process.
5357
Brian Quinlanaf38dc52010-09-21 12:28:43 +00005358- A new package ``concurrent.futures`` as defined by PEP 3148.

5485 return characters from the full Unicode range, even on narrow unicode builds
5486 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
5487 in Python is that unicodedata.numeric() now returns the correct value for
5488 large code points, and repr() may consider more characters as printable.

Victor Stinner47fcb5b2010-08-13 23:59:58 +00005506- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00005507 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
5508 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +00005514- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
5515 use PyUnicode_FromFormatV() to format the warning message.

5523 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00005524
Georg Brandl649971e2010-09-05 17:06:50 +00005525- Issue #9416: Fix some issues with complex formatting where the output with no
5526 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00005527
5528 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
5529 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00005868- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00005869 start byte and the continuation byte(s) are now considered invalid, instead of
5870 the number of bytes specified by the start byte. E.g.:
5871 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
5872 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
5873 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
5874 returned a single u'\ufffd'.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005946- Issue #8748: Fix two issues with comparisons between complex and integer
5947 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00005948 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
5949 (2) The comparison raised an OverflowError for large integers, leading to
5950 unpredictable exceptions when combining integers and complex objects in sets

Georg Brandl62069d32010-07-31 08:56:11 +00006081 where the right hand operand is a set of constants, by turning the set into a
6082 frozenset and pre-building it as a constant. The comparison operation is made
6083 against the constant instead of building a new set each time it is executed (a
6084 similar optimization already existed which turned a list of constants into a
6085 pre-built tuple). Patch and additional tests by Dave Malcolm.

6092 including: (1) a serious 'wrong output' bug that could occur for long (> 40
6093 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
6094 parsing certain long numeric strings corresponding to subnormal values, (3) a
6095 memory leak for some values large enough to cause overflow, and (4) a number
6096 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00006110- Issue #1811: improve accuracy and cross-platform consistency for true division
6111 of integers: the result of a/b is now correctly rounded for ints a and b (at
6112 least on IEEE 754 platforms), and in particular does not depend on the
6113 internal representation of an int.

Georg Brandl62069d32010-07-31 08:56:11 +00006139- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
6140 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
6141 long but the length of the range did not. Also fix several cases where
6142 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
6143 reversed(range(a, b, c)) with large arguments.

6256
Mark Dickinsone6fc7402010-08-06 18:55:26 +00006257- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
6258 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

6391 the performance hit anytime the cache is exceeded.

R. David Murrayef3d6bd2010-04-12 14:48:58 +00006775- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
Georg Brandl62069d32010-07-31 08:56:11 +00006776 character sets will now consistently use a Content-Transfer-Encoding of 7bit

Raymond Hettingerc50846a2010-04-05 18:56:31 +00006789- Add functools.total_ordering() and functools.cmp_to_key().
6790
Georg Brandl62069d32010-07-31 08:56:11 +00006791- Issue #8257: The Decimal construct now accepts a float instance directly,
6792 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00006793
6794 >>> Decimal(1.1)
6795 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00006800- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6801 InvalidOperation instead of returning False. (Comparisons involving a quiet
6802 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6803 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006804
Georg Brandl62069d32010-07-31 08:56:11 +00006805- Issue #2531: Comparison operations between floats and Decimal instances now
6806 return a result based on the numeric values of the operands; previously they
6807 returned an arbitrary result based on the relative ordering of id(float) and
6808 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
6809 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006810
Raymond Hettinger9c01e442010-04-03 10:32:58 +00006811- Added a subtract() method to collections.Counter().
6812
Barry Warsawd5f9bf52010-03-31 21:36:22 +00006813- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00006814 argument `-` which tells it to read files to compile from stdin. Each line is
6815 read on demand and the named file is compiled immediately. (Original patch by
6816 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00006818- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
6819 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00006820 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00006822- Comparisons using one of <, <=, >, >= between a complex instance and a
6823 Fractions instance now raise TypeError instead of returning True/False. This
6824 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6825 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00006827- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

6833
Antoine Pitrou910bd512010-03-22 20:11:09 +00006834- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00006835 didn't support chflags() (for example ZFS under FreeBSD). The error is now
6836 silenced.

6842 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
6843 reads and writes are always retried by OpenSSL itself.

Georg Brandl62069d32010-07-31 08:56:11 +00006868- The internals of the subprocess module on POSIX systems have been replaced by
6869 an extension module (_posixsubprocess) so that the fork()+exec() can be done
6870 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00006871
Georg Brandl62069d32010-07-31 08:56:11 +00006872- subprocess.Popen now has restore_signals and start_new_session features. The
6873 default of restore_signals=True is a new behavior compared to earlier Python
6874 versions. This means that signals such as SIGPIPE are not ignored by default
6875 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00006936- Issue #7633: In the decimal module, Context class methods (with the exception
6937 of canonical and is_canonical) now accept instances of int and long wherever a

Georg Brandl62069d32010-07-31 08:56:11 +00006961- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
6962 position when calling `truncate()`. It would previously change the file
6963 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00006964 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
6965
Antoine Pitroua32f9a22010-01-27 21:18:57 +00006966- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02006967 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00006968 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006969 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00006970 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007368- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007369 compared to other unix systems. In particular, os.getgroups() does not reflect
7370 any changes made using os.setgroups() but basicly always returns the same
7371 information as the id command. os.getgroups() can now return more than 16
7372 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00007728 threads could return successfully while some Thread objects were still
Georg Brandl88b95f92012-05-06 11:24:06 +02007729 referenced. This also introduces a new private function:

Benjamin Petersonbd35b032009-04-04 23:16:41 +00008016
8017Core and Builtins
8018-----------------
8019
Mark Dickinson865e01a2009-05-07 16:37:01 +00008020- Issue #5914: Add new C API function PyOS_string_to_double, and
8021 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
8022
Eric Smith741191f2009-05-06 13:08:15 +00008023- Issue #3382: float.__format__, complex.__format__, and %-formatting
8024 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
8025 affects nan -> NAN and inf -> INF.
8026
Mark Hammond5a607a32009-05-06 08:04:54 +00008027- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
8028 in all operations, including splitdrive, split, etc. splitunc() now issues
8029 a PendingDeprecation warning.
8030
Eric Smith63376222009-05-05 14:04:18 +00008031- Issue #5920: For float.__format__, change the behavior with the
8032 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
8033 to be like 'g' but with at least one decimal point and with a
8034 default precision of 12. Previously, the behavior the same but with
8035 a default precision of 6. This more closely matches str(), and
8036 reduces surprises when adding alignment flags to the empty
8037 presentation type. This also affects the new complex.__format__ in
8038 the same way.
8039
Martin v. Löwis011e8422009-05-05 04:43:17 +00008040- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
8041
R. David Murrayb18500d2009-05-04 22:59:07 +00008042- Issue #5890: in subclasses of 'property' the __doc__ attribute was
8043 shadowed by classtype's, even if it was None. property now
8044 inserts the __doc__ into the subclass instance __dict__.
8045
Antoine Pitrou244651a2009-05-04 18:56:13 +00008046- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
8047 sequences. Patch by Nick Barnes and Victor Stinner.
8048
Martin v. Löwise0a2b722009-05-10 08:08:56 +00008049- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00008050
Benjamin Petersond2e0c792009-05-01 20:40:59 +00008051- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
8052 received a new method, detach(). detach() disconnects the underlying stream
8053 from the buffer or text IO and returns it.
8054
Mark Dickinson33841c32009-05-01 15:37:04 +00008055- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
8056 floats with absolute value over 1e50. Also remove length
8057 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
8058 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00008059
Eric Smith741191f2009-05-06 13:08:15 +00008060- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00008061 format(complex(1, 2./3), '.5') now produces a sensible result.
8062
Mark Dickinsond3ca5572009-04-29 18:47:07 +00008063- Issue #5864: Fix empty format code formatting for floats so that it
8064 never gives more than the requested number of significant digits.
8065
Eric Smith6dc46f52009-04-27 20:39:49 +00008066- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
8067 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
8068
Eric Smithcc32a112009-04-26 21:35:14 +00008069- Issue #5835: Deprecate PyOS_ascii_formatd.
8070
Martin v. Löwis71efeb72009-04-26 01:02:07 +00008071- Issue #4971: Fix titlecase for characters that are their own
8072 titlecase, but not their own uppercase.
8073
Benjamin Peterson193152c2009-04-25 01:08:45 +00008074- Issue #5283: Setting __class__ in __del__ caused a segfault.
8075
Mark Dickinsonad476da2009-04-23 19:14:16 +00008076- Issue #5816: complex(repr(z)) now recovers z exactly, even when
8077 z involves nans, infs or negative zeros.
8078
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00008079- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00008080
Mark Dickinsone6a076d2009-04-18 11:48:33 +00008081- Issue #1869 (and many duplicates): make round(x, n) correctly
8082 rounded for a float x, by using the decimal <-> binary conversions
8083 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
8084 consistently agrees with format(x, '.2f').
8085
Benjamin Petersonae937c02009-04-18 20:54:08 +00008086- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
8087 some builtin types.
8088
Eric Smith0923d1d2009-04-16 20:16:10 +00008089- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
8090
Eric Smith35e84722009-04-16 20:21:28 +00008091- Issue #5515: str.format() type 'n' combined with commas and leading
8092 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00008093
8094- Implement PEP 378, Format Specifier for Thousands Separator, for
8095 floats.
8096
Mark Dickinson3370cce2009-04-17 22:40:53 +00008097- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008098 1e11, not 1e12. This avoids printing 13 significant digits in
8099 situations where only 12 of them are correct. Example problem
8100 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
8101 long time.)
8102
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008103- Issue #1580: On most platforms, use a 'short' float repr: for a
8104 finite float x, repr(x) now outputs a string based on the shortest
8105 sequence of decimal digits that rounds to x. Previous behaviour was
8106 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00008107 Another minor difference is that the new repr switches to
8108 exponential notation at 1e16 instead of the previous 1e17; this
8109 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008110
8111 There's a new sys attribute sys.float_repr_style, which takes
8112 the value 'short' to indicate that we're using short float repr,
8113 and 'legacy' if the short float repr isn't available for one
8114 reason or another.
8115
8116 The float repr change involves incorporating David Gay's 'perfect
8117 rounding' code into the Python core (it's in Python/dtoa.c). As a
8118 secondary consequence, all string-to-float and float-to-string
8119 conversions (including all float formatting operations) will be
8120 correctly rounded on these platforms.
8121
Georg Brandl5f90d792010-08-01 22:31:05 +00008122 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008123 this change does not apply.
8124
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00008125- Issue #5759: float() didn't call __float__ on str subclasses.
8126
Georg Brandlabc38772009-04-12 15:51:51 +00008127- The string.maketrans() function is deprecated; there is a new static method
8128 maketrans() on the bytes and bytearray classes. This removes confusion about
8129 the types string.maketrans() is supposed to work with, and mirrors the
8130 methods available on the str class.
8131
R. David Murraydc6da8a2009-04-09 22:16:43 +00008132- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
8133 its clarity and its speed.
8134
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008135- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00008136 to avoid compiler warnings.
8137
Walter Dörwald8dc33d52009-05-06 14:41:26 +00008138- Issue #3739: The unicode-internal encoder now reports the number of characters
8139 consumed like any other encoder (instead of the number of bytes).

8153
Raymond Hettingereb816952009-05-29 01:22:18 +00008154- Issue #5150: IDLE's format menu now has an option to strip trailing

Georg Brandlab6f2f62009-03-31 04:16:10 +00008286- Fix a segfault when running test_exceptions with coverage, caused by
8287 insufficient checks in accessors of Exception.__context__.
8288
Guido van Rossum0ad59d42009-03-30 22:01:35 +00008289- Issue #5604: non-ASCII characters in module name passed to
8290 imp.find_module() were converted to UTF-8 while the path is
8291 converted to the default filesystem encoding, causing nonsense.
8292
Benjamin Peterson09832742009-03-26 17:15:46 +00008293- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00008295- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
8296 the end sys.path, for compatibility with the system install of Python.
8297
Antoine Pitrou3a652b12009-03-23 18:52:06 +00008298- Issue #4688: Add a heuristic so that tuples and dicts containing only
8299 untrackable objects are not tracked by the garbage collector. This can
8300 reduce the size of collections and therefore the garbage collection overhead
8301 on long-running programs, depending on their particular use of datatypes.
8302
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00008303- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
8304 improve its performance. Long divisions and remainder operations
8305 are now between 50% and 150% faster.
8306
Mark Dickinsonbd792642009-03-18 20:06:12 +00008307- Issue #4258: Make it possible to use base 2**30 instead of base
8308 2**15 for the internal representation of integers, for performance
8309 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
8310 --enable-big-digits option to configure, which overrides the
8311 default. Add sys.int_info structseq to provide information about
8312 the internal format.
8313
Mark Dickinson081dfee2009-03-18 14:47:41 +00008314- Issue #4474: PyUnicode_FromWideChar now converts characters outside
8315 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
8316 and sizeof(Py_UNICODE) == 2.
8317
Eric Smith8ec90442009-03-14 12:29:34 +00008318- Issue #5237: Allow auto-numbered fields in str.format(). For
8319 example: '{} {}'.format(1, 2) == '1 2'.
8320
Antoine Pitrou652e7072009-03-13 19:25:20 +00008321- Issue #5392: when a very low recursion limit was set, the interpreter would
8322 abort with a fatal error after the recursion limit was hit twice.
8323
Matthias Klose042f1332009-04-04 14:32:42 +00008324- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

8370
Lars Gustäbel42e00912009-03-22 20:34:29 +00008371- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
8372 forever on incomplete input. That caused tarfile.open() to hang when used
8373 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinsonb40b9472009-03-29 16:58:21 +00008395 struct.error instead of returning b'\xff\xff\xff\xff'. The
8396 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

8413 used when using str.format() with str, int, and float arguments.
8414
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00008415- Issue #5249: time.strftime returned malformed string when format string
8416 contained non ascii character on windows.
8417
Benjamin Petersonf5b52242009-03-02 23:31:26 +00008418- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
8419 source has already been decoded into str.
8420
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00008421- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
8422 rotating the object pointer by 4 bits to the right.
8423
Mark Dickinson87ec0852009-02-09 17:15:59 +00008424- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8425 it now forces its argument to double before testing for infinity.
8426
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008427- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8428 returns a non-number type.
8429
Benjamin Peterson87618552009-02-08 15:00:52 +00008430- Issue #5182: Removed memoryview.__str__.
8431
Mark Dickinsonc008a172009-02-01 13:59:22 +00008432- Issue #1717: Removed builtin cmp() function, dropped tp_compare
8433 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00008434 the type definition cmpfunc. The tp_compare slot has been renamed
8435 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00008436
Georg Brandl1cdd83c2009-04-05 20:24:29 +00008437- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008438 were suppressing all exceptions. These include list() and bytearray().
8439
Mark Dickinson1124e712009-01-28 21:25:58 +00008440- Issue #4707: round(x, n) now returns an integer if x is an integer.
8441 Previously it returned a float.
8442
Antoine Pitroub52ec782009-01-25 16:34:23 +00008443- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8444 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8445 evaluation loop is compiled with a new dispatch mechanism which gives
8446 speedups of up to 20%, depending on the system, on various benchmarks.
8447
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00008448- Issue #4874: Most builtin decoders now reject unicode input.

8454
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00008455- Issue #4838: When a module is deallocated, free the memory backing the
8456 optional module state data.
8457
Mark Dickinson8055afd2009-01-17 10:04:45 +00008458- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008459 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00008460
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008461- Issue #4935: The overflow checking code in the expandtabs() method common
8462 to str, bytes and bytearray could be optimized away by the compiler, letting
8463 the interpreter segfault instead of raising an error.
8464
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008465- Issue #3720: Fix a crash when an iterator modifies its class and removes its
8466 __next__ method.
8467
Mark Dickinsone5e298f2009-01-12 20:49:19 +00008468- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
8469 function no longer attempt to call the __long__ slot to convert an object
8470 to an integer. Only the __int__ and __trunc__ slots are examined.
8471
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00008472- Issue #4893: Use NT threading on CE.

8475
Antoine Pitrouab868312009-01-10 15:40:25 +00008476- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
8477 common cases are optimized thanks to a dedicated fast path and a moderate
8478 amount of loop unrolling.
8479
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008480- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8481 collecting the oldest generation) so that allocating lots of objects without
8482 destroying them does not show quadratic performance. Based on a proposal by
8483 Martin von Löwis at
8484 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
8485
Vinay Sajip6268cbc2009-01-21 00:19:28 +00008486- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00008487 having been closed (for instance, a read() call could return some
8488 previously buffered data). Patch by Dmitry Vasiliev.
8489
Antoine Pitrou05608432009-01-09 18:53:14 +00008490- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8491 flag to work properly. Furthermore, when specifying -u, the text stdout
8492 and stderr streams have line-by-line buffering enabled (the default being
8493 to buffer arbitrary chunks of data).
8494
Raymond Hettinger35631532009-01-09 03:58:09 +00008495- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8496 instead of ints (reducing its size from 4 to 8 times thereby reducing
8497 Python's overall memory).
8498
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008499- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8500 an existing .py counterpart, override the co_filename attributes of all
8501 code objects if the original filename is obsolete (which can happen if the
8502 file has been renamed, moved, or if it is accessed through different paths).
8503 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8504
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008505- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8506 one byte. Also fixes the meaning of len() so that it returns the number of
8507 items, rather than the size in bytes.
8508
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008509- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8510
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008511- Issue #4747: When the terminal does not use utf-8, executing a script with
8512 non-ascii characters in its name could fail with a "SyntaxError: None" error.
8513
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008514- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
8515 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00008516
Antoine Pitrou7ddda782009-01-01 15:35:33 +00008517- Issue #3680: Reference cycles created through a dict, set or deque iterator
8518 did not get collected.
8519
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008520- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8521 where the tp_hash and tp_dict slots are both NULL.
8522
Georg Brandlccc47b62008-12-28 11:44:14 +00008523- Issue #4759: None is now allowed as the first argument of
8524 bytearray.translate(). It was always allowed for bytes.translate().
8525
Skip Montanaro80072cb2008-12-23 03:51:14 +00008526- Added test case to ensure attempts to read from a file opened for writing
8527 fail.
8528
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00008529- Issue #3106: Speedup some comparisons (str/str and int/int).
8530
Antoine Pitrouf289ae62008-12-18 11:06:25 +00008531- Issue #2183: Simplify and optimize bytecode for list, dict and set
8532 comprehensions. Original patch for list comprehensions by Neal Norwitz.
8533
Antoine Pitrou621601a2008-12-17 23:18:19 +00008534- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
8535 print elapsed times, not only when some objects are uncollectable /
8536 unreachable. Original patch by Neil Schemenauer.
8537
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00008538- Issue #3439: Add a bit_length method to int.
8539
Mark Dickinsonda2706b2008-12-11 18:03:03 +00008540- Issue #2173: When getting device encoding, check that return value of
8541 nl_langinfo is not the empty string. This was causing silent build
8542 failures on OS X.
8543
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00008544- Issue #4597: Fixed several opcodes that weren't always propagating
8545 exceptions.
8546
8547- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00008548 context manager returns a value that cannot be converted to a bool.
8549
Mark Dickinsonfd24b322008-12-06 15:33:31 +00008550- Issue #4445: Replace "sizeof(PyBytesObject)" with
8551 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
8552 bytes instances. On a typical machine this saves 3 bytes of memory
8553 (on average) per allocation of a bytes instance.
8554
Christian Heimesa872de52008-12-05 08:26:55 +00008555- Issue #4533: File read operation was dreadfully slow due to a slowly
8556 growing read buffer. Fixed by using the same growth rate algorithm as
8557 Python 2.x.
8558
Antoine Pitrou5504e892008-12-06 21:27:53 +00008559- Issue #4509: Various issues surrounding resize of bytearray objects to
8560 which there are buffer exports (e.g. memoryview instances).
8561
Georg Brandlf9734072008-12-07 15:30:06 +00008562- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
8563 method on file objects with closefd=False. The file descriptor is still
8564 kept open but the file object behaves like a closed file. The ``FileIO``

Antoine Pitrou08838b62009-01-21 00:55:13 +00008897- Issue #5008: When a file is opened in append mode with the new IO library,
8898 do an explicit seek to the end of file (so that e.g. tell() returns the

8930 appropriately when it is being used via socket.makefile() objects
8931 rather than delaying the close by waiting for garbage collection to do it.
8932
Raymond Hettingerb8baf632009-01-14 02:20:07 +00008933- Issue #1696199: Add collections.Counter() for rapid and convenient

Antoine Pitrou88909542009-06-29 13:54:42 +00009179- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
9180 regression tests in parallel, shortening the total runtime.
9181
Guilherme Polo2a998fa2009-06-21 17:40:07 +00009182- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
9183 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
9184 the same behaviour as test_ttkguionly (and now also test_tk) which is to
9185 skip the tests if DISPLAY is defined but can't be used.
9186
R. David Murraya21e4ca2009-03-31 23:16:50 +00009187- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00009188 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00009189 from test support, which does the conversion.
9190
Guilherme Polo9de29af2009-01-28 20:40:48 +00009191- Issue #5083: New 'gui' resource for regrtest.
